IntegraRack IR-40FSAB BallastRack Fixed-Adjustable Solar Module Mount – Black Zinc-Plated Steel

Easy to assemble

Inferior to Aluminum Versions

I bought 21 Aluminum 30 degree mounts and 9 steel. The steel had multiple defects (holes in wrong places, bent ends). The aluminum ones were perfect. Obviously they are still getting quality control dialed in on the steel versions, plus they can rust wherever they are scratched

Well made. As advertized.
